This invention relates to an improved type of a V f fountain pen provided with an improved starter and filling mechanism adapted to beengaged through the wall of the fountain pen barrel in co.-

, tainer is walled by a relatively longer end of'the pen Vbarrel and compressible.rubber-like struc'- ture mounted within the other end of thebarrel, and engaged by the container depressing member 'of the starter and filling mechanism, ,the latter including in the container means to freethe cond talner from the air, saidl means comprising an y air pipe similar to ones .which often occur in this type of .filling mechanisms.'-and the holding 'end I of this air pipe is mounted inw ther inner end of 1,0I

i operating relation with the inner resilient wall of the fountain pen ink container -and feed channel. L l' It is an object of this invention't'o provide a V17', fountain pen wherein a' semi-enclosed starter for.

it restricted depression of resilient rubber-like wall 10.01' 'the pen ink container is a relatively small `l so the side wall of the pen barrel and movably held if i,

-provide a' fountain pen wherein 'the outer side and round press button which has a hole therein, and is engaged through an opening in the side wall of thelpen barrel, and is removably securable to Vcontainer depression unit by medium of said .15. hole provided as mounting for securing member to allow the latter to hold the button in dependent position independently from the casing of the opening in the barrel.

. It'is also an object of this invention to provide a fountain pen with a container depression unit consisting .of a depression bar removably engaged between the pen barrel and resilient rubber-like wall ofthe pen ink container, and an operating plunger 4which has one end thereof adapted to while pressure against the starter may cause ythe bar to move inwardly,said plunger normally being loosely disposed in a full-length-fltting slot in in horizontalposition bymeans of an axial connection over the middle portion of the bar the length of said plunger with-a relatively long wirelike spring extended horizontally along the outer side ofthe -bar and firmly secured at the end of the bar to the latter and adapted for continuous inwardly pressure against the plunger at the l point of said axial connection.' Y It is furthermore an object of this invention to wall of the pen barrel has rotatably engaged in cylindrically concaved seat therein a relativelyl wide ring which vhas a number of circularly ar- 45 ranged and differently sized openings adapted to assume a dependent position'over and exposed through the barrel starting and filling members f of the container depression unit to initiate different degrees of external exposure of said members 50 thereby allowing to check the scopek of manual operation over the starting member, and to shelter the filling member when the ,latter is not in' use.

Figure rl is a fragmentary-elevational view of a and a portion ofthe'starting member exposed v side wall of the fountain-pen barrel illustrated in ing member and plunger of the depression unit. As shown on the drawing: Y

. 'I'he limproved vfountain pen` comprises an elonf gated'hollow barrel 9.r vr f Figure 16, and showing the sametring-exposing,l through a larger sized opening therein the start-y rushed into the ena or the barrera 'is apen i section I wherein in overlapping relation are se`- Qiii'cd a pen point i, IA, iB, 2 and 3, and a feed 1'5 Other and further important objects ofthis in bar 4A, the latter consisting of an outer portion removably adjacent (as shown) to the inner prtion thereof, and the bar 4A has a feed channel 4, A and 5.

The inner portion of the feed bar 4A is provided with an air pipe 1 having one (holding) end thereof mounted into the inner end of relatively deeper portion 5 4of the feed channel in straight line with outleading and relatively shallower portion 5A and 4 thereof, and the pipe 1 extends longitudinally through the major portion of the ink container B to within a relatively short distance from the closed end of said container, and the latter is walled by the longer end of the barrel 9 and a hollow rubber-like bulbous structure lli.

Removably engaged through a loosely fitting opening I5 in the barrel 9 is a container depression unit comprising a relatively small and round press button I4 having a hole I4A therein, and

the button I4 is adapted as starting member, and

an operating plunger I3.having one end thereof @mounted Ain kthe hole I4A and extended through saidholeto form al lifting hold ISA, and a depres- -sion bar 4I I rremovably engaged between the pen barrel 9 and rubber-like wall of structure III, and

a relatively long wire-like spring I2 firmly secured to the end IIA (Figure 5) of the bar II, and extended horizontally alongv the outer side of the bar II and at the middle portion ofthe latter forming a connecting axle through plunger I3.

The-closed ends of the barrel 9 and pen cap are l provided with air holes I6 and IGA respectively (Figure l). The feed channel 4, 5A and 5 is provided vwith the air channels 5B (Fig. 4) along its length. y i

In fragmentary elevational views illustrated in Figures 6 and 'l the outer wallof the pen barrel 9 lhas rotatably engaged in cylindrically concaved `seat therein a relatively wide ring I1 which has a number of circularly arranged and differently sized openings I1A, I1B and I1C of which each may assume a dependent position over starting member I4 and plungerl I3 of the depression unit by means of turning manually the ring I1 in its -seat in the barrel 9, for instance, from position shown in Figure 6 to position in Figure 7, l

Normally the operating lever or plunger I3 is ,y

in relatively horizontal position illustrated in Figures l and 7 and holdsthe starting member I4 by means of the hole I4A in normal semi-enclosed position -through a loosely fitting opening I5 in the barrel 9 (Figures 1 and 7), or through the same opening I5 covered by a relativelysmaller opening I1A (Figure 6) of the ring I1, and in said position the plunger I3 permits the structure III (Figure l) to remain in normally inflated position as shown' in Figure 1. Opening I5 in the barrel 9 and certain openings in the ring l1 (openings |1A and I1B, for instance) are smaller than diameter of an averagehuman finger and are adapted to restrict the latters entry into the inner chambers of the pen when the finger presses against the button I4 mounted in saidopenings.

When it is desired to initiatev the` start of ink flow in the pen by executing restricted depression of the container, structure lli may be partially compressed vby medium of a ngex"V pressing against the extending portion of button I4 (Figures 1, 6 and 7) in which case due to described construction the compression of structure I0 will be restricted by degree of normally exposed extension of the button I4 over barrel 9 (Figure 1) or ring I1 (Figure 6), and the finger pressure will be restricted by the outer wall of barrel 9 (Figure 1) or ring I1 (Figure 6).

When it is desired to fill the fountain pen the pen point I, IA, IB, 2 and 3 and a small portion of pen section 8 immediately adjacent to the point are projected into a supply of ink.

The ring I1 is turned to allow the relatively larger opening I1C therein to assume position over button I4 and plunger I3 (Figure 7) thereby fully exposing said members, then the plunger I3 by means oi its liftinghold I3A (Figures l and 5) is` swung outwardly into perpendicular position illustrated in Figure 2.

When in its position shown in Figure 2 the plunger I3 is adapted to be slidably projected inwardly through a slot in the opening I5 to cause the bar II to compress or collapse the resilient rubber-like wall of `structure IIl as illustrated in Figure 3.

Upon release of the operators nger from the depressed plunger I3 the wall of structure IIi'together withthe bar I I acts to project the plunger I3 outwardly to permit the same to be again manuallv pushed inwardly to repeat the collapsing operation against the wall of structure Iii.

In the pen illustrated in Figure 1 the first collapsing and releasing operations would fill ther ing the container 6 would be proportional amount of air forced out by collapsing the struc? ture I0, and the latter, as shown, walls only a relatively small portion of said container 8;

While the container 3 is empty the air being forced out may easily escape to outleading portions 5A and 4.of the feed channel directly via portion 5 thereof, but when container l is partially nlled with ink the latter would block the air from entering said 'portion 5 of the channel. and the air pipe 1 as long as one end thereof remains above the ink level will provide easier ave nue for air to escape to the outleading portions 5A and 4 of the feed channel.

The filling of the illustrated pen is accomplished by repeating described operations against structure Impeach collapsing operation forcing out some air via pipe 1 and portions 5A and 4 of the channel,l and each releasing operation from container 6.' t

Tov decrease number of the operations required to fill the container 5 to its full capacity in cooperation with the pen feed channel the air pipe 1 has its holding end mounted direct into the said channel (the end 5 thereof) in straight line with and to the channels outleading portions 5A and 4 to allow easier and directly aimed avenue of air escape for greater amounts of air to be forced out with each repeated collapsing operation against structure IIi.

Before removing the pen point from the ink supplyl the lever I3 should be restored to normal position illustrated in Figure 1 by pushing manually the button I4 towards the submerged end of the pen whereby lever I3 will be moved from perpendicular position shown in Figure 2 and by .forceof spring I2y snapped into position shown in Figure 1. Then, if it is desired to shelter the plunger I3, the ring I1 may be turned from position illustrated in Figure 'l to a new position depending on operators desire in refer- 4ence to degree of exposure to be allowed the button I4. VIf the ring I1 is turned to position illustrated in 'Figure 6 only relatively small portion of said button I4 will be exposed through the relatively smaller opening I1A of ring I1. If

Fountain pens embodying described features and when designed for carrying may be equipped for further safety with a shut-off valve, for instance, ball valve 8 (Figure 1) which is constructed within the scope of my U. S. Patent #2,098,528 and, as described therein,l will shut off the ink in container 6 mounted over said valve. AThus, if the starter and filling structure are accidentally compressed while the pen is in carrying position, the ink will not leak out from said container.

While specic embodiments of this invention are herein shown and described, it is and will be clearly understood, oi course, that variations within the scope of accompanying claims may be resorted to without jeopardizing this patent pro- 'I tection, and that the various details of construction may be varied through a wide range without departing from the vprinciples of this invention as described in one or more of-the following claims, and is therefore not the purpose to limit the patent granted hereon otherwise thanV necessitated by the said scope of the appended claims.
